ELECTRIC-HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 694,018, dated February 25, 1902.y

A Application filed June 17, 1.901. Serial Noi 64,807. (No model.)

To alZZ whom t may concern:

Beit known that I, EMIL KASTNER, a citizen of theGerman Empire, residing at Berlin, Prussia, Germany, haveinvented certain new and useful Improvements in Electric-Heating Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enablev others skilled in the art to which it appertains t make and use the same.v

The present invention relatesto an apparatus for electrically heating liquids-as, for instance, beer, milk, or the like-which is convenient for use in public places as well as in private.

The apparatus is shown in the accompanying drawings, in which-Y- n y Figure l is a longitudinal sect-ion of the same. Fig. 2 is a cross-section of the heater; Fig. 3, a longitudinalv section of a modified form of apparatus, and Fig. 4 is av-plan View of the latter. 1

The device consists of an electric Wire or conductor otof great resistance, which may be inclosed in a casing b, which latter can besides be tilled with a non-conducting material for heat-transmitting purposes. The upper part cof the casing is preferably constituted by non-conducting material, to which is applied the contact-screws d for connecting the apparatus to an electric source. A ther- Y mometer e is attached to the casing and isolated from the latter by a heat-isolating partition or massf.

The apparatus is introduced into the recep- 4tacle containing the liquid to be heated and of the heater, in which the electrical source-f for instance, a dry batteryv g'-is connected with the apparatus. Said element remains, of

course, outside the liquid-receptacle and the apparatus can be brought into action instantaneously by means of a convenient switch or the like.

If desired, the apparatus can be made transportable, so as to be carried in the pocket, in which case the battery is preferably of flat form, as shown in plan view in Fig. 4c.

Having now particularly described and ascert-ained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is V 1. In an electric" heater, the combination,

with a portable casing, and resistance-wires inclosed therein; of a thermometer secured against one side of the casing for indicating the temperature of the fluid into which the said casing and thermometerare plunged, and non-heat-'conducting material between the said casing and thermometer vwhereby the direct passage'of heat from the casing to the f thermometer is prevented, substantially as set forth.

2. In an electric heater, the combination,
